We are Efterklang, a group of engineers, designers and technical specialists delivering award-winning work in the Nordic region and worldwide since 1956. We create sound environments and solve vibration issues at all scales and in all sectors. Used in the right way, sound can be a bearer of communication and information. Sound can surprise you, make you alert, encourage you to shop more, or simply make you feel good. In the same way that furnishing and lighting can set an atmosphere and ambience in a room – so can sound. Efterklang provides comprehensive audio branding through sound design in public environments and commercial media such as TV, radio and digital media. We create sound concepts, sound productions, sound environments and acoustic solutions. We also choose and install the technology and administer the system, often through our own software platform Twang. Our clients are shops, malls, banks, offices, restaurants, hotels, museums and national parks. By taking care of the entire process, from idea to sound content and technical installation, we customize each solution based upon the preconditions. We always consider and base our solutions on the existing sound environment and a pre study digging in to the brand itself to increase recognition, harmony and result. In our team you find sound architects, project managers, technicians, and sound and music producers in our in-house studio team.
